SCRs are the switching devices for this unusual DC to DC converter that is suited for the ubiquitous 5V USB power source as well as numerous other applications. This novel power circuit topology uses ...

This Design Idea stems from the limited availability of IC voltage regulators that can meet key USB-power specs, coupled with the need for turn-on sequencing and rise-time control at each output. As ...

My understanding, all USB ports provide 5v. I am trying to get voltage from TV USB port to power an input switch relay box (would turn on when TV turns on from standby and starts powering the USB ...

Designers of USB Type-C small form factor devices can now create always-on rails with the ultra-low quiescent current MAX77596 buck converter from Maxim. Next-generation products that use the high ...

Low clamping voltage, high surge transient voltage suppressors (TVS) from Alpha and Omega Semiconductor (AOS) are designed for Vbus protection. The AOZ8621UNI series of six TVS are suitable for USB ...
